Together, the projects are estimated to save nearly 46,000 metric tons of carbon dioxide (CO2) annually and more than $7 million in annual energy costs across nearly 6.5 million square feet, the release stated.

According to the release, 12 of the projects attained an estimated CO2 emissions reduction of 50 percent or more — meeting AIA and industry goals for a 50 percent CO2 reduction in new construction by 2030.

"Through the American Institute of Architects, America leads the way in energy efficiency and sustainable developments," said Al Armendariz, EPA regional administrator.

"Those acknowledged today show great commitment to preserving the environment and reducing the carbon footprint," Armendariz added.
